What else can I help you with?
What is the name of the non cellular layer that attaches epithelial tissue to other layers?
The basal lamina, made up of the lamina densa and the lamina lucida. In cases where to layers of epithelium abut one another, the basal lamina is referred to as a basement membrane.
What is the connective tissue found beneath all types of epithelium?
The connective tissue found beneath all types of epithelium is called the basement membrane. It provides structural support to the overlying epithelial cells and helps in anchoring them to the underlying tissues. The basement membrane also plays a role in filtration and diffusion of substances between the epithelial cells and the underlying tissues.
What connective tissue does all epithelial tissues rest upon?
All epithelial tissues rest upon a layer of connective tissue known as the basement membrane. This membrane provides support and anchors the epithelial cells in place, allowing them to function effectively.
What is the framework for many soft organs?
reticular fibers
What forms supporting tissue in walls of thymus and spleen?
The supporting tissue in the walls of the thymus is made up of a framework of reticular fibers and reticular cells. In the spleen, the supporting tissue consists of reticular fibers, fibroblasts, and smooth muscle cells. These structures provide structural support and help maintain the architecture of these organs.
Difference between basal lamina and basement membrane?
The term "basal lamina" is usually used with electron microscopy, while the term "basement membrane" is usually used with light microscopy. The structure known as the basement membrane in light microscopy refers to the stained structure anchoring an epithelial layer. This encompasses the basal lamina secreted by epithelial cells and typically a reticular lamina secreted by other cells.
What is the difference between the basement membrane and the basal lamina in terms of their structure and function?
The basement membrane is a complex structure made up of two layers, the basal lamina and the reticular lamina. The basal lamina is the innermost layer of the basement membrane and is composed of proteins like collagen and laminin. It provides structural support and acts as a barrier between different tissues. The basal lamina also plays a role in cell adhesion and signaling. On the other hand, the basal lamina is a thin layer of extracellular matrix that is found underneath epithelial and endothelial cells. It helps anchor these cells to the underlying connective tissue and regulates the passage of molecules between the cells and the surrounding tissue.
What is the structure that attaches epithelial cells to the basal lamina?
The structure that attaches epithelial cells to the basal lamina is called hemidesmosomes.
What composes basement membrane?
Areolar connective tissue composes basement tissue. This is a soft packaging tissues that features a jellylike matrix. This type of tissue is one of the most widespread throughout the human body.
What type of epithelium lack a basal lamina?
Hepatocytes and endothelia (eptihelium lining vessels)
What is the name of the non cellular layer that attaches epithelial tissue to other layers?
The basal lamina, made up of the lamina densa and the lamina lucida. In cases where to layers of epithelium abut one another, the basal lamina is referred to as a basement membrane.
Where is the basal lamina of axon and ganglion cells?
I would to know that
What is the difference between the basal lamina and the basement membrane in terms of their structure and function?
The basal lamina is a thin layer of extracellular matrix secreted by epithelial cells, while the basement membrane is a thicker structure that includes the basal lamina along with additional layers produced by connective tissue cells. The basal lamina provides structural support and acts as a barrier, while the basement membrane also serves as a filter and plays a role in cell signaling and tissue organization.
What is the thin non living layer that anchors epithelium to connective tissue?
Basement membrane is the thin, non-living layer that anchors epithelium to connective tissue. It provides structural support and helps regulate the movement of molecules between the epithelium and connective tissue.
How is junctional epithelium attached to enamel?
The junctional epithelium attaches to enamel by means of internal basal lamina .
The lamina propria is composed of?
The Mucosa
what cells is returned to the basal lamina to continue the pool of dividing germ cells?
Spermatogonia cells are returned to the basal lamina to continue the pool of dividing germ cells in the male reproductive system. These cells undergo mitosis to maintain the population of germ cells, with some differentiating into primary spermatocytes that will later undergo meiosis to produce sperm.
